As part of its collaborative mission, every year CDL purchases perpetual rights to scholarly digital content using end-of-year funds. This growing collection of content provides permanent digital rights on behalf of future generations of UC faculty and students in varied disciplines across the sciences and humanities.

Often CDL’s perpetual purchases result in a waiver or substantial reduction in ongoing annual subscription fees, thus offering long-term cost savings to campuses.

This year, in addition to CDL’s purchases, a number of campuses stepped forward to offer their end-of-year funds for acquisitions on behalf of the consortium or interested campuses. The following is a summary of scholarly content recently purchased by CDL and UC libraries:

American Chemical Society (ACS) Legacy Archive
Purchased by Los Angeles, Merced, Berkeley and LBL on behalf of all campuses.

C19: Index to the 19th Century (ProQuest)
Requested by several bibliographer groups in 2007, approved by CDC and purchased by CDL on behalf of all campuses.

Institute of Physics Archive
Europhysics Letters and Physica Scripta purchased by San Diego on behalf of all campuses.

Nature Archives
1869-1949 archive purchased by CDL on behalf of all campuses. UC now owns all Nature content back to Volume 1, Issue 1. This was a one-time buy-out of annual fees for all Nature archives, purchased by CDL on behalf of all campuses. As a result of this purchase, ongoing annual fees for Nature archives are now waived in perpetuity.
